I have created following controller:

class ControllerCommonTestSMS extends Controller
{
    function index()
    {
       //  action
    }
}

But if I add the following line, it throws an error that the function is undefined:

$this->customer->isLogged();

class ControllerCommonTestSMS extends Controller
{
    function index()
    {
       if (!$this->customer->isLogged()) {

    }
}

this is working fine.
